1. A scaled down raster image processor for reduced cost, reduced complexity processing of print image data to be printed on a particular print engine, said scaled down raster image processor comprising:

  • a master controller circuit which receives a job description file and, in response to said job description file, prepares displays lists and transfers fonts for storage in a font image memory;

    a scaled down controller circuit that operates in accordance with display lists received from said master controller circuit and said stored fonts to generate a digital representation of an image;

    a bit image memory associated with said scaled down control circuit, wherein said bit image memory stores the digital image representation generated by said scaled down controller; and

    a personality module for said particular print engine, said personality module operable to request and read raster data from said bit image memory and to provide said raster data to said print engine to operate said print engine and thereby produce an image.
